Read covariance matrix from `.cov` file
NMreadCov(file, auto.ext, tableno = "max", simplify = TRUE)The ".cov" covariance Nonmem matrix file to read
If `TRUE` (default) the extension will automatically be modified using `NMdataConf()$file.cov`. This means `file` can be the path to an input or output control stream, and `NMreadCov()` will still read the `.cov` file.
The table number to read. The ".cov" file can contain multiple tables and will often do so if using SAEM/IMP methods. Default is "max" which means the last table is used. Alternative values are "min" and "all" or numeric values. If "all" or multiple numeric values are used, a list is returned. However, see `simplify` too.
If `TRUE` (default) and only one table is returned (say using tableno="max") only that matrix is returned as a matrix object. If `FALSE` or multiple tables are returned, the result is a list.
A matrix with covariance step from NONMEM or a list of such matrices (see `simplify`)
